A snapped cable is possibly to blame for the tragic death of a Cirque du Soleil performer who plummeted to the ground in front of a live audience. Sarah Guyard-Guillot dropped more than 50 feet after a safety wire failed during the Cirque du Soleil show "Ka". Guyard-Guillot had a son and a daughter, just eight and five years old. The LA Times reprots this is the second death during the company's 30 year history.
